Title: Method and equipment for controlling dc motor
Inventor: SAKATA MASASHI
IPC: H02P7/295
Filed: 1994-03-25
Abstract: PURPOSE:To control the rotational speed of a DC motor by forming a shaping waveform in a pulse shaping waveform by making the pulse width of a section having large amplitude in the shaping waveform smaller than that of a section having small amplitude and adjusting the pulse width as a whole. CONSTITUTION:Automatic control is conducted in such a manner that the voltage of a smoothed waveform, voltage V1 applied to a DC motor M, is detected by a voltage detecting section 12, the voltage V1 is fed back to a control pulse generating section 11, and the voltage V1 is stabilized. The speed of a DC motor M is controlled by varying the set value of the voltage V1 by adjusting a rheostat VR1. A waveform distortion factor is reduced because currents are made to flow extending over the whole phase angle of a rectifying waveform, and a capacitor C1 and a choke coil CH1 are miniaturized because the frequency of the pulsation component of a puls rectifying waveform is made higher than a commercial AC power supply SAC. Accordingly, an equipment is compacted.

Title: Radio-communication apparatus and method for measuring reception level of the apparatus
Inventor: OKAMURA KAZUNORI
IPC: H04B17/318
Filed: 1998-02-20
Abstract: PROBLEM TO BE SOLVED: To average in a short time a long-section reception level of a radio- communication apparatus. SOLUTION: A measured value of a short-section reception level for a unit time (t) is input as a V value into a reception operation part 4 of a radio reception part 1. A radio control part 7 adds the input measured short-section reception level value to a short-section reception level value added up to a previous time, and stores the value. The radio control part 7 divides the stored added short-section reception level value by a measurement count of times, thereby obtaining a long-section reception level average value by the V value. The radio control part 7 converts the long-section reception level average value from the V value into a dB value in accordance with a conversion table stored in a memory part 9. At ST307, the long-section reception level average value converted into the dB value is sent to a transmission power control part or a line quality estimation part.

Title: Method for grinding and forming curved surface by numerical control
Inventor: JIYON SURAU
IPC: B23Q15/00
Filed: 1991-01-30
Abstract: PURPOSE: To simplify the control in a curved surface grinding forming method by numerical control. CONSTITUTION: The grinding surface participating in grinding in a grindstone cross-sectional shape passing through the rotary shaft is formed in a circular arc shape by using a rotary grindstone 1, and is controlled so as to maintain only a contact state of the circular arc-shaped grinding surface and the target profile surface while maintaining a distance (r) between curvature center 3 of the circular arc and a target profile equal to a radius of curvature of the circular arc of the grinding surface. This contact state is maintained so that a normal in a contact point with the grinding surface of the target profile exists in a central angle of the circular arc of the grinding surface, and that a difference between an inclination ψ of this normal and an inclination θ of a bisector of the central angle of the circular arc falls within a constant range.  The constant range is half of the central angle of the circular arc. A grinding point C on the grinding surface moves in a circular arc plane. The target profile can be ground and formed without controlling a posture of the grindstone one by one, and local abrasion of the grinding surface can also be prevented.

Abstract: PURPOSE:To dispense with calibration by an interferometer, by mounting a reflecting mirror at a position on the opposite side of a probe and arranging both of them on the same straight line as the optical axis of an objective lens to fix the reflecting mirror to the focal position of the objective lens. CONSTITUTION:A lever 4 having a probe 1, a minute reflecting mirror 2 and a balance wt. 3 mounted thereto is held to a holder 6 by a bearing 5, and the holder 6 is fixed to the mirror cylinder 9 of an objective lens 8 while the mirror 2 is positioned in the vicinity of the focal position of the objective lens 8 by a clamp knob 7. A probe position adjusting knob 10 is operated to accurately match the mirror 2 with the focal position of the lens 8. When a measuring object is moved to X- and Y-direction by a specimen position adjusting device, the probe 1 contacted with the surface of the object displaces up and down correspondingly to the uneven shape of the surface of the object. Hereupon, the mirror 2 simultaneously displaces up and down in the same quantity. The converged laser beam 11 passed through the lens 8 is reflected by the mirror 2 and counted in digital quantity as the up-and-down movement of the probe 1, that is, the up-and-down movement of the mirror 2 by a laser interferometer and the uneven shape of the surface of the object is detected.

Abstract: PURPOSE:To improve the reliability of a mask structure for lithography, by bonding a mask material holding thin film to inner and outer holding substrates in the outer peripheral surfaces of the film which are located below the top surface of the inner holding substrate while the top surface of the outer holding substrate is located below the top surface of the inner holding substrate. CONSTITUTION:A mask material 1 which is an about 0.7mu thick Au thin film is formed in a desired pattern on a holding thin film 2 of polyimide having a thickness of 2-12mum. The thin film 2 is bonded in its periphery to annular holding substrates 3 and 5 in a predetermined manner. The holding substrates 3 and 5 are made of quartz or stainless steel and the adhesive may be a solvent or solvent-free type. The inner holding substrate 3 is not applied with the adhesive 4 in its top flat surface 3a, but applied only in the surface 3b which is located outside the surface 3a and intersects it at an angle theta. The angle theta is selected to be 15-30 deg.. Accordingly, the bonding strength between the mask holding thin film 2 and the holding substrates 3 and 5 is enhanced sufficiently so that the film 2 is not peeled off even if pulling stress is applied to the film 2 to maintain the flatness thereof, and a mask structure having excellent flatness and high reliability can be obtained.
